Caution: Within 5.15 to 5.25 MHz bands, UNII devices are restricted to indoor operations to reduce
any potential harmfull interference to co-channel Mobile Satelite Systems (MSS) operations.
This Indigo device is shipped with FCC-compliant firmware. In order to ensure regulatory-compliant
channel usage in a particular country, special geographic-specific firmware is available for customer
production assemblies which restricts channel usage. Examples include ETSI-compliant firmware, MKK
-compliant firmware etc. Since the end user does not have the ability to alter this firmware, regulatory
compliance is ensured.

FCC Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in
accordance with the instructions, it may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try and correct the
interference by one or more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the distance between the equipment and the receiver.
3. Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected.
4. Consult the dealer or an experienced radio/TV technician for help.
Export restrictions:
This product or software contains encryption code which may not be exported or transferred from the
US or Canada without an approved US Department of Commerce export license.
FCC Guidelines for Human Exposure
The EIRP was measured for the lower, middle and highest frequencies used by the transmitter. The
results in Table xx below are based on a safe distance between antenna and operator of 8 inches (20
centimeters).The equipment therefore fulfills the requirements on power density for general population /
uncontrolled exposure of 1.0 mW/cm² and therefore complies with the requirements of FCC OET
Bulletin 65 including supplements A, B and C.
Channel 36 Channel 48 Channel 64
Measured EIRP (mW) 70.8 67.6 69.2
Specific absorption
Ratio SAR ( mW/cm²) 0.06 0.05 0.06
Table xx: Compliance specifications
Caution: To comply with FCC RF exposure compliance requirements, a separation distance of at least
20 cm must be maintained between the antenna of this device and all persons.
